hey guys

my buddy has a 2006 F350 6 liter. EGR delete arps sct tuned s&b intake and exhaust. well last week he noticed some oil dripping out of the tailpipe as it was warming up he checked it and it was down like 5 quarts. went to ford they pulled the turbo the y pipe is clean no oil the downpipe is covered in oil. so they put reman turbo internals in and sent him on his way. well the new turbo is doing the same thing. so it went back into the shop they put 2 diff reman turbo internals in and same problem. the turbo housings seem to be brand new. I cant figure it out the housings dont have any cracks or anything in them. it doesnt make any sense. sorry for the long post thanks for any help guys. oh and the truck only has 40k on it

You can buy a fairly cheap pressure/vacuum gauge at an autoparts store, then buy some tubing that will fit on the dipstick tube (and you may need an adapter to fit on the pressure gauge end). Buy enough tubing to be able to run the tubing and gauge into the cab. Take a drive and see what the pressure is. The max crankcase pressure spec (from Ford) is 0.3 psig. All the materials are available from the autoparts store.

thanks for the ideas guys what happened was the crankcase breather hose became plugged and the crankcase pressure was blowing the turbo seals

That is a pretty big hose. What plugged it?
